back in the day it was around 200 bucks (2012 ish). today that same piece is probably 300 to 350 for the same piece.
Jon, I believe you but the Orange Book part numbers don’t show any discernible difference between no sunroof and sunroof. The numbers for the horsehair seat pad shows 811 753 as 2800CS up thru 3.0CS USA 2240134 and 2250066, 819 107 remainder of 3.0CS, and 833 321 as the MY 74 which has a longer lower seat cushion so only three options.Looked it up and there are 2 Front Seat numbers for 4/71-75 and 2 Frame numbers for 4/71-75. Seats end in 811-753 and 819-107. Frames end in 825-445 and 825-446. Not definitive proof but a reasonable level that they are different.
We learn something every once in a while that makes us better stewards for the Coupes.
Regards, Jon
i honestly don't know how you would track them in the orange books since the sunroof model is not really differentiated in those books (by VIN)Jon, I believe you but the Orange Book part numbers don’t show any discernible difference between no sunroof and sunroof.

The frame number you list as 825445 and 446 shows as the back of the seat L and R but if it means the entire frame then: 812 560 is early 2800CS, 811 707 is 3.0CS USA from 224 0134 and 2250066 as above, 812 095/6 L and R shows remaining 3.0CS and 825 445/6 as USA MY 1974.
Another mystery from BMW!
say hi to Eric for meI'm meeting with Eric (Anton) on Thursday so will see what items/options he still has from his design. Anything specific you'd like for me to get from him? I'm a very late joiner to this game since it sounds like he created these a number of years ago and from his own admission he sent the plans away to someone else a bit ago, but may be worth picking his brain just to see what did work, didn't work, etc.
It would be seat structure or the horsehair pad.i honestly don't know how you would track them in the orange books since the sunroof model is not really differentiated in those books (by VIN)
Scott -- one thing I thought about, and your prior post seems to start down this path, is whether I could find an existing armrest/cover that could be used.i honestly don't know how you would track them in the orange books since the sunroof model is not really differentiated in those books (by VIN)
that piece looks pretty wide. ideally narrower than 150mm and shorter than 350mm. right now i am a believer in the henry ford approach - you can have any color you want as long as its black. or you can change it yourself or paint / dye it depending on material. the love of the idea of a manufactured sliding piece is that you aren't inventing / manufacturing something difficult. if you had to recover a top, okay, not the end of the world - even without getting into color, texture is often a problem.At a certain point the question becomes whether it's easier/cheaper to have a frame built into which a more readily available hinged part can be implemented, like the one you posted earlier, or something like this..probably would need to look around to confirm the right width, length, etc but may be worth considering. Also then comes the question of coloring - I believe that Anton's had the armrest in the interior leather color which makes it look more customized and perfect but obviously comes at increased complexity - is my red the same as your red vs someone else who needs black or tan.
absolutely. i am looking at cars between 2000 and 2020 ... and the preference is 2015 to 2023 for exactly the reasons you mention ... and with cars that were produced in huge numbers. think VW, Toyota, etc. i looked at BMW but they all had funny shapes.And at that point the customization answer may be "here's the frame that the E9 group has built at $X cost, here's a link to a readily available drop-in hinged portion along with simple instructions of how to assemble them together, take the stock part to an upholsterer if you want custom leather/vinyl". Probably the best method to avoid having to deal with custom.
Also would be ideal to find a part from a car built in the last 10-15 years so that we can ensure availability (maybe) for the near future. Sourcing parts from a 1990s car is possible but can start to get spotty as the years go on.
